MATERIAL AND METHODS:  In this cross-sectional study, patients showing at least three or more classical or warning signs like polydipsia, polyuria, polyphagia, and general weakness were considered UDM cases. Detailed oral examination for gingivitis, periodontitis, halitosis, xerostomia, and tongue manifestations was done followed by the hemoglobin A1c (HbA1c) analysis...

BACKGROUND: Cardiac evaluation using transthoracic echocardiography before noncardiac surgery is common in real-world practice. However, evidence supporting preoperative echocardiography is lacking. This study aims to evaluate the additional benefit of preoperative echocardiography in predicting postoperative cardiovascular events (CVE) in noncardiac surgery. METHODS: This study is designed as a multicenter, prospective study to assess the utility of preoperative echocardiography in patients undergoing intermediate- or high-risk noncardiac surgery...

OBJECTIVE: To investigate the clinical usefulness of diffusion tensor imaging (DTI) and tractography in the prediction of outcomes after traumatic cervical spinal cord injury (SCI) and to assess whether the predictability is different between DTI and tractography administered before and after surgery. METHODS: Sixty-one subjects with traumatic cervical SCI were randomly assigned to preop or postop groups and received DTI accordingly. Among the patients who had DTI before surgery, we assigned 10 patients who had received repeated DTI examinations at 8 weeks after injury to the follow-up group...

PURPOSE: Thoracic outlet syndrome (TOS) is a rare disorder involving compression of the brachial plexus, subclavian artery, and subclavian vein. There is a paucity of data for this pathology's surgical treatment within pediatrics. The objective of this study is to explore the presentation, management, and outcome of pediatric TOS. METHODS: A retrospective chart review was conducted for 44 patients at a single institution undergoing surgery for TOS. Data was collected on demographics, pre- and postoperative factors, and outcomes...

OBJECTIVE: To determine factors associated with failure of same-day trial of void (SDTOV) following holmium laser enucleation of the prostate (HoLEP). BACKGROUND: HoLEP is increasingly utilized for patients with benign prostatic hyperplasia. Advancements in technology have improved operative efficiency and hemostasis making same-day, catheter-free discharge possible. METHODS: We conducted a retrospective review on 190 patients undergoing HoLEP from July, 2021 to January, 2022 by a single center...

BACKGROUND: Prostate biopsy (Bx) sampling-based diagnosis of prostate cancer (PCa) has well-described inaccuracy when compared against whole gland analysis upon prostatectomy. Although upgrading of PCa Grade Group (GG) is often described, the occurrence and prognostic implications of downgrading PCa GG at the time of radical prostatectomy (RP) is less understood. Our objective was to evaluate whether downgrading PCa GG at the time of RP was associated with future tumor behavior. METHODS: The SEER database was searched from 2010 to 2017 and patients were included if they were assigned pathological grades on both Bx and RP specimen...

This study aimed to examine the effectiveness of photorefractive keratectomy (PRK) in treating patients with cycloplegic hyperopia from +1.00 to +7.00 diopter using Allegretto wave Eye Q 400. This study was conducted on 25 patients with cycloplegic astigmatism ≤1 diopter and cycloplegic hyperopia between +1.00 and +7.00 diopters in 47 eyes, who successively entered into the study within 6 months and underwent PRK. Prior to PRK surgery, all the patients were examined for cycloplegic refraction (astigmatism and hyperopia), slit lamp, keratometry, fundus, and best-corrected (BCVA) and uncorrected visual acuity (UCVA) testing...

INTRODUCTION: The physical examination in anterior cruciate ligament (ACL) injuries is extremely important, and the Lever test is commonly utilized on ACL evaluation. However, the number and scope of studies on the Lever test is limited. In this prospective cross-sectional study, we aimed to evaluate the effectiveness of the diagnostic values of Lachman, Pivot Shift, Lever, and Anterior Drawer tests in terms of quadriceps atrophy and case phase in ACL injuries. METHODS: In this prospective study, diagnostic values of Lachman, Pivot Shift, Lever, and Anterior Drawer tests were examined on 189 patients with positive MRI results as the gold standard...

PURPOSE: To assess the long-term outcome of graft insertion by taco technique through a 2.8-mm clear corneal incision in patients undergoing Descemet's stripping automated endothelial keratoplasty (DSAEK). METHODS: This is a retrospective interventional case series of 77 eyes of 75 patients who underwent DSAEK in a tertiary eye hospital. The DSAEK donor grafts were folded to an uneven 70/30 taco and held at a single point using Utrata forceps. All insertions were through a 2...

AIM: The aim is to discuss the clinical characteristics, time, anatomical vascular distribution, radiological features, functional outcomes after stroke and possible pathophysiological mechanisms of acute ischemic stroke (AIS) that develop after cardiac surgery. METHOD: A total of 3,474 patients, who underwent cardiac surgery between 2015-2020, retrospectively were analyzed. Forty-nine patients, who developed AIS and had brain CT and diffusion MR images during hospitalization, were included in the study...

Although immunoassays are the most widely used protein measurement method, aptamer-based methods such as the SomaScan platform can quantify up to 7000 proteins per biosample, creating new opportunities for unbiased discovery. However, there is limited research comparing the consistency of biomarker-disease associations between immunoassay and aptamer-based platforms. In a substudy of the TRIBE-AKI cohort, preoperative and postoperative plasma samples from 294 patients with previous immunoassay measurements were analyzed using the SomaScan platform...

Elective lower segment caesarean section patients are routinely instructed to fast from food for 6h before surgery, with clear fluids up until 2h before surgery. We conducted an audit examining the true fasting times of mothers undergoing an elective caesarean section and the incidence of urinary ketones before and after introducing a preop carbohydrate drink (Nutricia preOp 400ml) to be administered to all patients at 6am on the day of surgery. We audited 50 patients prior to introducing the preop carbohydrate drink and 54 patients after the introduction of a carbohydrate drink...

INTRODUCTION: Arthroscopic Latarjet surgery is a technique developed to minimize invasive surgical treatment of anterior shoulder instability. However, compared to an open Latarjet operation, it is considered more technically demanding. The aim of our study was to assess its mid-term success rate in the hands of a surgeon with sufficient experience. PATIENTS AND METHODS: We included 32 patients with recurrent anterior shoulder instability in the analysed cohort who had undergone arthroscopic intervention according to Latarjet as a revision after a previous failed Bankart operation or in the case of the significant bone loss of the glenoid...

PURPOSE: HER2 +- amplified breast cancer patients derive benefit from treatment with anti-HER2-targeted therapy. Though adjuvant treatment is based on final pathology, decisions regarding neoadjuvant chemotherapy are made in the preoperative setting with imaging playing a key role in staging. We examined the accuracy of pre-operative imaging in determining pathological tumor size  (pT) in patients undergoing upfront surgery. METHODS: Early (cT1-T2N0) HER2 + breast cancer patients who underwent upfront surgery between 2015 and 2016 were identified from a prospective institutional database...

PURPOSE: Hallux valgus is a disease that can be treated with many different surgical procedures. In our study, we aimed to compare patients with and without dorsal neutralization plate after distal metatarsal osteotomy and fixation with compression screws. METHODS: The files of 59 patients with 89 feet operated with the diagnosis of moderate degree hallux valgus have been examined retrospectively. Hallux valgus angles, AOFAS, VAS and satisfaction scores, time to return to work of both groups were compared...

BACKGROUND: Our understanding of the relationship between plasma and cerebrospinal fluid (CSF) remains limited, which poses an obstacle to the identification of blood-based markers of neuroinflammatory disorders. To better understand the relationship between peripheral and central nervous system (CNS) markers of inflammation before and after surgery, we aimed to examine whether surgery compromises the blood-brain barrier (BBB), evaluate postoperative changes in inflammatory markers, and assess the correlations between plasma and CSF levels of inflammation...

INTRODUCTION: Fall risk is an acknowledged but relatively understudied concern for older patients undergoing shoulder surgery. The cause is multifactorial, but includes: advanced age, impaired upper extremity function, the use of shoulder abduction braces, and postoperative use of opioid medications. No previous study has examined preoperative fall risk in patients undergoing elective shoulder surgery. Previous literature looking at fall risk in elective orthopedic procedures has predominantly focused on falls occurring in the hospital setting, although falls have also been shown to occur in the outpatient setting...

BACKGROUND: With increasing health care expenditures, knowledge about the benefit and costs of surgical interventions such as total shoulder arthroplasty (TSA) becomes important for orthopedic surgeons, social insurance programs, and health policy decision makers. We examined the impact of TSA on quality of life (QOL), direct medical costs, and productivity losses and evaluated the cost-utility ratio of TSA compared with ongoing nonoperative management using real-world data. METHODS: Patients with shoulder osteoarthritis and/or rotator cuff tear arthropathy indicated for anatomic or reverse TSA were included in this prospective study...
